getting the bolt out involves removing the BBL. It can eb done by the DIY'er with a few basic tools and a lot of patience.

However before I did that If I were you I'd remove all the wood and plastic bits and hose the action out with a can O brake parts cleaner.

With the 742 look a the top of the receiver inside just behind the chamber. If it's got marks from the bolt chewing into it there's no point in even cleaning the thing as it's now a wall hanger.

Hopefully you have a chamber brush that came with the rifle. It`s a bronze bristle brush with zigzag bent wire handle with loop in the handle end. Pull bolt back and insert brush into the bore and push/pull back and forth to clean chamber. Reverse the brush and put a cloth into the loop and push/pull that back and forth iside the chamber. Push out the trigger pins and drop the trigger assembly. You can spray some silicon inside the open cavity and then wipe out the area with the cloth. Some foam cleaner sprayed into the barrel and let sit for 15 minutes. Use a pull thru bore brush from chamber to muzzle to clean out the barrel. Using a metal rod inserted into the muzzle will ruin the crown and ruin accuracy. Wipe out the trigger cavity again and you are done. That`s the way to clean the Remington 742. The bolt cannot be removed without removing the barrel. Most important care for this rifle is to keep water/moisture out of the bore. Rust in the chamber will ruin the rifle. There are no parts available for the Rem. 742 so I don`t advise removing the rails after dropping the trigger assembly . The rails can be easily bent while reassembling. Dropping the trigger assembly and using a foam cleaner in the barrel and pull thru bush is all that can be done with it.
I traded my Rem. 742 for a Browning Abolt .270wsm. Better accuracy and easier to clean. I hunted with my Rem. 742 about 15 years and took perhaps 40 deer with it. Not accurate with relaods. Would only shoot the factory 180 grain bullets accurately. Not accurate with 150 gr. or 165 gr. Mine was .308 win. caliber. Cleaning from the muzzle with metal rod affected accuracy. It needed a recrown but, I didn`t have it done. If yours works alright after you do the above cleaning procedure, sell it, trade it. Get either a Browning BAR or a bolt action of your choice.

thanks guys, I will do the spray/clean/brush job, and keep it - it shoots so well, no recoil, and still after 30 years is plugging along at 1 1/4 inch groups
thanks again

Get a CJ Weapons Chamber Maid and clean the crap out of the chamber.

I forgot to mention that the gas system is self cleaning. You don`t need to do anything to it.
